MAINTENANCE
Regular maintenance is the best prevention for costly
downtime or expensive, premature repair. The following
pages contain suggested maintenance information and
schedules which the operator should follow on a routine
basis. For more detailed information, order the correct parts
manual for your unit. Remain alert for unusual noises, as they
could be signaling a problem. Visually inspect the machine
for any abnormal wear or damage. A good time to detect
potential problems is while performing scheduled
maintenance service. Correcting the problem as quickly as
possible is the best insurance.
12.1 MOWER BLADE MAINTENANCE
Check the mower blades daily. They are the key to power
efficiency and well-groomed turf. Keep them sharp -- a dull
blade will tear rather than cut the grass, leaving a brown
ragged top on the grass within a few hours. A dull blade also
requires more power. Replace any blade that is bent, cracked
or broken.
WARNING
Never attempt to straighten a bent blade by heating, or weld
a cracked or broken blade as the blade may break and cause
serious injury. Replace worn or damaged blades.
WARNING
Never work with blades while key is in the ignition switch.
Turn key to “OFF” position, remove key from switch and
disconnect battery cables by pulling inward on RED battery
quick disconnect handle in battery box compartment. Block
up mower when you must work under it. Wear gloves when
handling blades. Always check for blade damage if mower
strikes a rock, branch or other foreign objects!
